T8b949e/**

* Covers the local-only power-channel labels: the direct setter round-trips through the [List]<[String]> column

* converter, and a routine device-sync upsert (which never carries labels) must not clobber the user's saved labels.

*

* JVM-only: the preservation case re-`upsert`s an existing row, and that nested suspend `@Transaction` (upsert reading

* back a `@Relation` row) throws a bare SQLException under Robolectric's SQLite; the logic itself is pure Kotlin.
